Comparison of Treatment Outcome of Cabergoline According to Target Prolactin Levels in Patients With Prolactinoma

An interventional study of Cabergoline in Pituitary Adenoma, Prolactinoma and Pituitary Tumor, sponsored by Seoul National University Hospital. Status unknown at 1 site in Korea, Republic of. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2020-03-18.

Why
  1. The study's listed conditions name Prolactinoma, a narrower term within Pituitary Neoplasms.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The aim of this study is to investigate whether inhibition of serum prolactin levels below normal range during cabergoline administration may reduce the recurrence rate after drug withdrawal in patients with prolactinomas.

Read the detailed description

Prolactinoma patients will be assigned to a experimental group that maintains serum prolactin levels below 5 ng/mL and a control group that maintains normal serum prolactin levels. After that, cabergoline will be maintained at a therapeutic dose for 130 weeks. After cabergoline is discontinued, patients will be followed up with serum prolactin measurement for 52 weeks.

In context

Prolactinoma Reclassified

28 studies on the registry are indexed under Prolactinoma; 5 are open to participants now.

This study's planned enrollment of 68 is above the median of 55 across 14 interventional studies indexed under Prolactinoma.

Lead sponsor

Seoul National University Hospital is the lead sponsor of 1,900 studies on the registry; 274 are open to participants now.

Of its 12 completed or terminated interventional studies of FDA-regulated products, 2 (17%) have results posted.

Compared within Prolactinoma, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Pituitary Neoplasms. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adults, male or female aged 19 years or older
  • diagnosed with prolactinoma
  • No previous history of surgery, medication, or radiation therapy

Exclusion criteria

Exclusion Criteria:

  • Invasive prolactinomas except invading cavernous sinus
  • Taking dopaminergic medications
  • Taking medications that can affect serum prolactin level (including estrogenic hormone, oral drugs, intrauterine devices)
  • Hyperprolactinemia due to secondary causes
  • History of pituitary apoplexy within the last 3 months
  • Patients with mental illness that should avoid dopamine agonists
  • Patients with history of cardiac valve diseases
  • Patients with history of pulmonary fibrosis, retroperitoneal fibrosis, and cystic fibrosis
  • Moderate degree of hepatic or renal insufficiency (IDMS Modification of Diet in Renal Disease (MDRD GFR) \<45 ml/min/1.73m2)
  • Patients with cabergoline reaction
  • Pregnant or breast feeding patients
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
